Frequently Asked Questions - QuietComfort Ultra Earbuds BOSE

How to connect the earbuds to my smartphone?

Open the charging case, then press and hold the button on the back of the case until the earbud status light flashes blue slowly. Enable Bluetooth on your smartphone and select Bose QC Ultra 2 Earbuds from the list. You can also use the Bose app for a guided setup.

How to change the ear tips?

Hold the earbud, gently flatten the ear tip and pull to remove it. Align the new ear tip on the nozzle and press until you hear a click. Be careful not to pull on the edge of the ear tip to avoid tearing.

How to use immersive audio?

Immersive audio places the sound in front of you. You can adjust it via the Bose app or by setting a shortcut. Press and hold on the assigned earbud to cycle through settings: Motion (sound follows your head), Still (sound remains fixed), or Off.

How to clean the earbuds and case?

Remove the ear tips and stability bands, wash them by hand with a mild detergent and rinse. Clean the ear nozzles with a dry cotton swab. Clean the charging contacts with a dry cotton swab. Clean the case only with a dry cotton swab. Never insert any tools into the nozzles.

What to do if the earbuds are not charging?

Check that the earbuds are properly magnetically aligned in the case and that the charging contacts are clean. Make sure the USB cable is properly connected and the wall charger is working. If using a wireless charger, align the button on the back of the case with the center of the charger. If the problem persists, try a different cable or charger.

How to reset the earbuds and case?

Place both earbuds in the case and close the lid. Connect the USB cable to the case and a power source. Press and hold the button on the back of the case for 30 seconds until the case light turns off. This reset does not delete settings.

How to change listening mode?

Make sure you have configured a shortcut to cycle through modes via the Bose app. Then press and hold on the assigned earbud until you hear the name of the desired mode (Quiet, Aware, Immersion or a custom mode), then release.

What is the actual battery life?

With immersive audio off, battery life can reach up to 6 hours. With immersive audio on, it is about 4 hours. The charging case provides up to 3 additional full charges. A quick 20-minute charge offers 2 hours of playback.

Are the earbuds water resistant?

Yes, they are certified IPX4, which means they are resistant to sweat and weather (splashes). However, they should not be submerged or used in the shower or while swimming.

How to use the shortcut on the earbuds?

By default, the shortcut allows you to cycle through modes. You can change it via the Bose app (Settings > Shortcuts). Assign a shortcut to the right or left earbud to quickly access immersive audio, switch devices, launch Spotify Tap, or activate device voice controls.

NOTE: Medium eartips are attached to the earbuds. For help identifying the eartip sizes, see page 18.

Stability bands (sizes 2 and 3)

NOTE: Size 1 bands are attached to the earbuds. For help identifying the band sizes, see page 18.

USB Type-C ^® to USB-A cable

NOTE: If any part of your product appears to be missing or damaged, don't use it. Visit support.Bose.com/qcue2 for troubleshooting articles, videos, and product repair or replacement.

The Bose app lets you set up and control the earbuds from any mobile device, such as a smartphone or tablet.

Using the app, you can verify the earbud fit, manage Bluetooth connections, manage earbud settings, adjust the audio, choose your voice prompt language, and get any future updates and new features made available by Bose.

NOTE: If you've already downloaded the Bose app for another Bose product, you can add the earbuds from the product list screen.

DOWNLOAD THE BOSE APP

1. On your device, download the Bose app.

BOSE

GET IT ON Google Play

1. Follow the app instructions to add the earbuds.

The earbuds are rated IPX4 water resistant. They are designed to be sweat and weather resistant but aren't meant to be submerged under water.

CAUTIONS:

• Do NOT swim or shower with the earbuds.
• Do NOT submerge the earbuds.

Two symbolic icons: a circle with a diagonal line and a teardrop-shaped object emitting droplets (no text or symbols present)

NOTES:

• To prevent corrosion, regularly clean the charging contacts on the earbuds with a dry, soft cotton swab or equivalent.
• IPX4 isn't a permanent condition, and resistance might decrease as a result of normalwear.

INSERT THE EARBUDS

1. Insert the earbud so the eartip gently rests at the opening of your ear canal.

NOTE: Each earbud is marked with either an R (right) or L (left).

R R/L marking

1. Slightly rotate the earbud back until the eartip creates a comfortable seal at your ear canal and the stability band rests against your ear ridge.

NOTE: You may need to rotate the earbud back and forth for the eartip to create a comfortable seal. However, rotating it too far back or forward may impact audio and microphone sound quality.

Stability band Ear ridge Insert Rotate

1. Check the fit (see page 16).

2. Repeat steps 1 - 3 to insert the other earbud.

When you insert the earbuds, the audio is personalized to your ears for the best audio performance and noise cancellation.

NOTE: If you're sharing the earbuds, place them in the charging case to clear the audio personalization between each user.

CHECK YOUR FIT

For the best fit, audio performance, and noise cancellation, use a mirror to make sure you're using the correct size eartips and stability bands. You may need to try a different size eartip or stability band for each ear.

TIP: You can also check your fit using the Earbud Seal Test in the Bose app. You can access this option from the Settings menu.

Eartips

FIT WHAT TO CHECK

Proper fit		The eartip gently rests at the opening of your ear canal to create a comfortable seal. Background noise should sound muffled. NOTE: Noise cancellation may impact the ability to hear muffled noise.
Too much pressure		The eartip feels uncomfortable and squished in your ear canal.
Too loose		The eartip rests too deep in your ear canal, feels loose in your ear, or falls out when you move your head.

Stability bands

FIT WHAT TO CHECK

Proper fit		The band doesn’t stick out or feel squished against your ear ridge.
Too big		The band is sticking out or feels squished under your ear ridge.
Too small The band doe		idge.

TRY ANOTHER SIZE

Wear the earbuds for an extended period of time. If the earbuds don't feel comfortable or secure, or noise cancellation or sound quality isn't as expected, try another size eartip or stability band.

You may need to try all three eartip or band sizes or use a different size eartip or band for each ear.

Eartips

Three sizes of eartips are included with the earbuds: small, medium, and large.

Three identical diagrams showing concentric circles with shaded inner regions, no text or symbols present.

Medium eartips come attached to the earbuds. If they feel too small, try large eartips. If they feel too big, try small eartips.

Stability bands

The stability bands are marked with size 1 (small), 2 (medium), or 3 (large) and an R (right) or L (left).

Three identical wireframe diagrams of a ring or container with labeled points (1, 2, 3) and 'R' on each side, no text or symbols beyond labels.

Size 1 bands come attached to the earbuds. If they feel too small, try size 2 bands.

CHANGE THE EARTIPS

1. Holding the earbud, gently squeeze the eartip and peel it away from the earbud.

Immersive Audio works on any streaming content from any source, taking it to new heights with better sound clarity and richer sound quality.

NOTE: When you make or receive a phone call, Immersive Audio is temporarily set to Off (see page 32).
